Does anybody know where I can get a new sump plug, like in the picture? It's for my Cupra R (225 BAM engine). Mine has been leaking for a while now, and every service I buy a new one which says it fits my engine, but they have all been wrong so far I have replaced the copper washer, and it's still leaking. Not loads, but drops of oil keep forming at the bottom of the sump, right under the sump plug. I also have to keep topping the oil up, after long periods of time. It's just getting annoying now lol
